The basin is an indispensable sanitary ware in people's daily life. Therefore, we must be extra careful when purchasing ceramic basins. The ceramic wash basins on the market are diverse in shape and rich in color. How do we choose economical and durable ceramic basins? Here are some tips.

1, glazed finish, brightness

When purchasing, first of all, like ordinary white ceramic wash basins, attention should be paid to glaze finish and brightness. It can be observed from the side of the ceramic under strong light, and the good glaze should be free of stains, pinholes, blisters and bubbles. The surface is very smooth; the light is reflective and uniform; it can also be used on the surface by hand. Gently stroke, the hand sensor is very smooth and delicate. Good glaze finish and brightness, pure color, not easy to hang dirty, easy to clean, long-term use is still bright as new.

2, water absorption index

The water absorption rate is an index for judging the adsorption and penetration ability of a ceramic product to water. It is understood that after the water is sucked into the ceramic, the ceramic will have a certain expansion, and it is easy to cause the glazed surface of the ceramic surface to be cracked due to swelling. It can be seen that the lower the water absorption rate, the better the quality of the ceramic product. According to the national water absorption rate standards, sanitary ceramics with a water absorption rate of less than 3% are high-grade ceramics. When purchasing, you should pay more attention to the manufacturer's instructions and try to choose products with low water absorption.

3, craft, pattern, color

Most of the high-end hand-painted color basins are made of under glaze ceramics, which is also the best ceramic technology at present. Therefore, it is necessary to pay attention to the identification when buying, in case the unscrupulous dealers use the glaze color to fill the glaze, to fake the real. The under glaze decoration pays attention to the pen-like freehand brushwork. It must be drawn by hand, not printed, decal, and the color should be bright.
